T b all whom it mcty concern:

Be it ;known that l, Vroron ScHLuYER, a citizen of theUnited States, residing at Anderson, in the county of Madison and 5 State of lndiana, .have invented a new an useful Self-Maintaining Lubricating System for Deep-Well Pumps, of which the fol lowing is a specification, I

It is the ob'ect of my invention to provide an effective ubricating system for deep well pumps, where filtered water is used as the lubricant and unfiltered water and the sand and dirt whichitcarries in the well are kept awayvfrom the bearings, and to maintain the supply of filtered water regardless of the leakage thereof whichmay occur and which in the preferred form of my invention I provide for in order effectively to prevent ingress of unfiltered water at the pump bearingsl v The accompanying drawing illustrates my invention: Figure 1 is a vertical central section through the upper end of a deep-well pump embodying my invention; Fig, 2 is a transverse section'through such upper end; and Figs. 3 and 4: are vertical central sections through two embodiments of-my invention which maybe provided at the lower end of the well. 3 The pump casing 10 at the bottom of the well has a bottom inlet 11 and a top discharge12, which latter opens to an upwardly extending discharge pipe 13 whichulead's'upward through thewell to a discharge fitting 14: at the top of the well. Within the pump casing 10 is a runner 15, of any conyenient type, the pump being shown as a single ru ner though obviouslyf it may have-any desired number of runners. The pump runner (or runners) is-mounted vertical shaft 16, which extends up axially through-the pipes12 and 13 and is driven in any suitable manner by a driving means at the top. Above the runner 15 abearing 17 is provided for the vertical shaft 16, such being suitably supported so that it p "does not interfere with the upward flow of 'water discharged from such runner, and such bearing 17' has a flaring upper end 1 8 19 of a small lubricant-circulating pump of which the runner 20 isfixed on the shaft 16 within such casing 19. The inlet 'of the runner 20 is upward, tending to suck downward through the upward extension 21 of the casor annnnson, INDIANA, 'EANY, or rnnranaroms, INDIANA,

ing 19; and its chamber 22 provided in the casing 19. Preferablythe lower end of the casing 19 is separated by a plate 23 from. a chamber 24: formed in the flaring upper end 18 of the bearing 17, which plate is provided with a gland 25 around the shaft 16, or around a onsaid. shaft if that is preferred; and the discharge chamber 22 is connected to the chamber 245, as by a pipe 26, to supply liquid, to the chamber 2 1 under pressure from the runner 20 and thus the lubricant is forced downward through the bearing 17 against any tendency of. unfiltered water to rise through such bearing. The chamber 22 may be connected to any other parts to be discharge is outward into a" Patented Sept. ieai.

lubricated, if desired, in addition to; or 1n place of the bearing 17, for simplicity being shown connected to that particular hearing, The upward extension 21 of'the casing 19 is connected to the lower end of a lubricantconducting pipe 30 which surrounds the shaft 16 and extendsupward from such extension 21 through the discharge fitting 14,

as is clear from Fig. 1. The shaft 16 may be provided with any suitable bearings 61 at desired points, such bearings being within .the pipe 30. Near its upper end, preferably fitting 1 1 is integral. This settling tank is providedwith a plurality of curved baffles 35 opening provide a plurality of spaces 36 which together constitute a serpentine settling passa'geway nected to the-inner space 36, referably at a oint considerably above the bottom thereof. The outer space 36 is connected to the upper end of a return pipe-37 which extends down into thewell beside the pipe 30 and is connected at its lower end to the discharge chamber 22 of the lubricant-circulating ump. The settling tank is provided with a filling and overflow pipe 38, which leads into the outer space 36.

When the device is in operation, the run ner 20 draws the lubricating water from the inside space 36 of the tank 33, through the pipe 32 and down to lubricate the bearings 31, and discharges such lubricating water into the discharge chamber 22, whence the water is in part realternately at opposite ends, to s leading to the pipe 32, which is conthrough the pipe 30 around said shaft,

upward, from t .e inlet of said e to nter space 36 anlr and in 'o a '3 dischar ed L} n .4. Y ie pipe throngs, tllfi oearings er pump parts to be in, o

a El 1 P a 1: .1 L 2 J pecial y on account or D e outi ow tnr ugh the no openings through the n 21 of the casin 19 for from the well, which openan; 40 communicateeither dispace within the water-dis- 12 a the main water pump, by s ll, as shown. in Fig. 3, or by way of a .pipe having a filter 13 at its outer end with the space within the well outside the pump casing and discharge pipe, as shown in Fig. .4. The passage 40 provides a water inlet directly to the intake of the runner of the lubricant-circulating pump, and the filters 41 or 43 effectively strain such water and prevent ingress of dirt or sand. .The filling and overflow pipe 38 permits the proper level to be maintained in the tank 83, either by allowing any excess to overflow in more water is drawn through the openings 40 than is lost or by permitting additional water to be poured intosuch tank, which is preferably provided with a water level gage a l for indicating the water' lcvel; In case anysand or dirt is carried in through the openings 40, it is taken. directly by the runner 20 without first passing through any of the bearings 31, and if carried up through the pipe 37 into the tank 33 is there permitted to settle out of the water as the latter travels through its serpentine course toward the pipe 32, so that the water finally supplied o such pipe 32 and therethrough to the pipe will be substantially free from sand and dirt.

The inflow of water through the openings l0, primarily produced by the suction of the lubricant-circulating pump, may be augmented by an injector action from the downwardly flowing main stream to such pump, by giving the openings 40 a component of discharge in the direction of such stream flow to produce a sucking Pitot-tubc action and by making the inner wall of the extension 21 in the general form of a Venturi tube into whichthe openings 40 communicate at about the beginning of the ex paneling portion thereof.
